The double force film blowing machine tells you what to pay attention to during the use of the film blowing machine

The double force film blowing machine tells you what to pay attention to when using the film blowing machine as follows:

In the process of using the film blowing machine, you must strictly observe the precautions for the use of the film blowing machine, which can reduce mechanical loss and extend the service life of the machine. If you encounter other problems during use, please contact our factory!

1. Since electrical components may be damaged during transportation or the wire ends may fall off, you should strictly check first. In order to ensure personal safety, you must connect the ground wire when opening the organ, then turn on the power supply, and then strictly check whether the motors are running correctly at all parts, and pay attention Whether there is leakage phenomenon.

2. When installing, pay attention to adjusting the center line of the extruder head and the center of the traction roller to keep it horizontal and vertical, and not to deviate from the skewed.

3. As the outer diameter of the winding gradually increases during winding, please pay attention to the coordination of the traction speed and the winding speed, and please adjust it in time.

4. After the host is turned on, pay close attention to the operation of the host, and adjust, modify, electrical instruments and controllers in time to ensure its normal operation.

5. The main engine gearbox and traction reduction box should be refueled frequently, and the gear oil should be replaced. Please replace the new gear oil within 10 days of use for the new machine to ensure the normal operation of all rotating parts. Pay attention to refueling to prevent jamming and overheating damage. Check the tightness of each connection part to prevent the bolt from loosening.

6. The compressed air in the bubble tube should be kept in an appropriate amount, because the compressed air will leak out during the towing process, please add it in time.

7. Frequently clean and replace the filter screen in the machine head to prevent clogging, and prevent the inclusion of iron, sand, stone and other impurities in the plastic particles to avoid damage to the screw barrel.

8. It is strictly forbidden to rotate without material. When the barrel, tee, and die have not reached the required temperature, the host cannot be started.

9. When starting the main motor, start the motor first and then slowly accelerate; turn off the main motor, first decelerate and then shut down.

10. When preheating, heating should not be too long or too high to avoid clogging of the material port.

The variable frequency speed regulation driving system of the plastic film blowing machine consists of two parts: one is the frequency converter of the extrusion main motor, and the other is the frequency converter of the traction motor. Their control is very simple, and the speed of the motor can be controlled by the panel. Keyboard or external set potentiometer to adjust. The design of the mold (die head) is also related to the quality of the blown film, the surface finish of the spiral body and the inner wall of the mold barrel, the absolute balance of the spiral (the absolute balance of each shunt groove), the pressure of the cavity in the mold, and the pressure of the die. The extension angle, the depth (height) of the die setting section, the ratio of the die gap to the thickness of the blown film, the total height of the die, the wall thickness design of the mold barrel (heat preservation), the design of the outer heating ring (the uniform heating temperature) Distribution), etc., are the key points that must be carefully designed to blow the "perfect" film.

Speed ​​up and down time: Since plastic machinery does not need to start and brake frequently, there is no strict requirement on the speed up and down. The basic principle of the film blowing machine is not to exceed the rated current, but the sealing and cutting machine should be preset as short as possible.
